Paired Mannich condensates of alkyl phenols

Abstract

Normally liquid final Mannich condensates prepared by reacting a para C 1 -C 15 alkyl phenol with formaldehyde and a first polyoxyalkylene diamine to form an intermediate Mannich condensate that is reacted with formaldehyde and a second polyoxyalkylene diamine to form a final Mannich condensate, the first and second polyoxyalkylene diamines having the formula: ##STR1## wherein R represents hydrogen or methyl and R' represents an alkyl group containing 1 to 4 carbon atoms or cyanoethyl group, and n represents positive numbers having a value of 1 to about 6, the final Mannich condensate having the formula: ##STR2## wherein X and Y are polyoxyalkylene amine groups derived from the first and second polyoxyalkylene diamines and formaldehyde.

We claim: 
     
       1. A compound of the formula: ##STR28## wherein X represents a polyoxyalkylene amine group having the formula: ##STR29## wherein: n represents a positive number having a value of 1 to 6, R represents hydrogen or methyl,   R' represents a cyanoethyl group, and   R" represents a straight chain or branched alkyl group containing from 1 to 15 carbon atoms.   
     
     
       2. A compound of the formula: ##STR30## wherein X represents a group having the formula: ##STR31## wherein Y represents a group having the formula: ##STR32## wherein: n represents a positive integer having a value of 1 to 6, n' represents a positive integer having a value of 1 to 6,   R represents hydrogen or methyl,   R' represents a straight chain or branched alkyl group containing from 1 to 4 carbon atoms or a cyanoethyl group, and   R" represents a straight chain or branched alkyl group containing from 1 to 15 carbon atoms.   
     
     
       3. A compound as in claim 2 wherein R represents H and R' represents a cyanoethyl group. 
     
     
       4. A compound as in claim 2 wherein R represents H and R' represents an alkyl group containing 1 to 4 carbon atoms. 
     
     
       5. A compound as in claim 2 wherein R represents H and R' represents an isopropyl group. 
     
     
       6. A compound as in claim 2 wherein R represents methyl and R' represents a cyanoethyl group. 
     
     
       7. A compound as in claim 2 wherein R represents methyl and R' represents an alkyl group containing 1 to 4 carbon atoms. 
     
     
       8. A compound as in claim 2 wherein R represents methyl and R' represents an isopropyl group. 
     
     
       9. A compound as in claim 2 wherein R in formula (II) represents H, R' in formula (II) represents an isopropyl group, R" represents an alkyl group containing 9 carbon atoms, R in formula (IV) represents methyl and R' in formula (IV) represents a cyanoethyl group.
